Emma Watson, one of the stars of the Harry Potter franchise, has enrolled for acting classes at university.

Despite playing Hermione Granger over the past decade, Watson remains modest about her abilities.

"I think I'm actually the worst person in the class," she said.

The 20-year-old student put her career on hold to enrol at Brown University in America, where she also studies European women's history and Ovid's Metamorphoses.

She told Vanity Fair magazine her first few days at the Ivy League university in Rhode Island were unhappy.

"It was just awful," she said. At her first party she felt as if she had "walked into an American teen movie".

She was also worried that fellow students would resent her attempts to combine her studies with more glamorous activities. However, she was relieved to discover that her room-mate has no interest in Harry Potter.
